Questions about CSPX

How much would $500 a month in CSPX be worth after 20 years?

At an assumed 8% a year minus the 0.07% fee, $500 a month for 20 years would grow to an estimated $291,961, from $120,000 paid in. Real returns will differ, so try the lower and higher scenarios too.

Is CSPX accumulating or distributing?

CSPX is accumulating: dividends are reinvested inside the fund automatically, so you don't receive cash payouts.

What is the CSPX expense ratio?

CSPX has a total expense ratio (TER) of about 0.07% a year (data checked November 2026; confirm with iShares before investing). The calculator subtracts this from the return when fees are switched on.

Where is CSPX domiciled?

CSPX is domiciled in Ireland (a UCITS fund). Investors outside the US often prefer Irish-domiciled funds for their lower US dividend withholding tax and simpler estate rules.
